Just days after debuting two new songs at a show at the Glass House in Pomona, New York's Yeah Yeah Yeahs announced Monday that they'll release an album, "Mosquito," on April 16, the post-punk band's first since "It's Blitz!" in 2009.

Like "It's Blitz!," the upcoming disc was produced by Dave Sitek of TV on the Radio and Nick Launay, who's also worked with Nick Cave and the Cribs, among others. LCD Soundsystem's James Murphy oversaw one track, and rapper Kool Keith makes a guest appearance in his Dr. Octagon guise.

"We took a more playful, lo-fi approach to songwriting," singer Karen O said in a statement. "Much of the music was demo'd in our little basement studio in Manhattan with drum machines, a ... sample keyboard and tons of delay, which we called 'the soup.'

"I think this record has more moodier and tripped-out songs than you've ever heard from us," she added. "You might catch some roots-reggae and minimalist psychedelia influences in there."

Karen O, guitarist Nick Zinner and drummer Brian Chase have spent the last few years pursuing interests outside the group.
